For stuff like this I am surprised they didn't stop paying Apple sooner. Just dumb to cough up 30% to Apple for a subscription like this. Way to expensive and Apple can't justify a 30% cut. Apple fix your ****!!
It's 30% for the first year then 15% Onward for subscriptions.
The Amount of profit google make it huge anyway and the Platform it provides is priceless.
Subscribing through Apple is anonymous if you want it to be...won't be the case with Google payment.
Apple disabled my app years ago and refused to allow any new builds until I implemented In App purchasing. I had been handling everything via PayPal. If YouTube can get away with not paying the Apple premium, then why should I have to?
If you want to set up a payment method an login though a website service... then have people log into your app you can. You then have to manage the Users / Payments and verifications yourself. It's just a log on to a service for apple. Audible works like this. You cannot buy books through the app as that direct competitor to iBooks... but they could do subscriptions though the iPhone in apps purchasing but they prefer to have it all though Amazon payments unsurprisingly.
Personally I think it's worth the 30% ( going down to 15% in the second year ) if I were doing it... What was Paypal cut anyway?
